摘要:
某钢铁企业采用微滤+纳滤+反渗透工艺，对厂区中水回用工程产生的反渗透浓盐水进行处理，处理后的回用水作为焦化厂循环水系统补水。实际运行结果表明，该浓盐水处理系统运行状况良好，处理工艺合理，产水率达到78.8%，直接运行费用为4.62元/m3。回用水水质满足《城市污水再生利用 工业用水水质》（GB/T 19923—2005）中工艺与产品用水水质标准，最终超浓水水质满足《钢铁工业水污染物排放标准》（GB 13456—2012）中水污染物特别排放限值标准后用于冲渣或掺入烧结配料，实现了浓盐水废水零排放。
Abstract:
The combined process of microfiltration, nanofiltration, and reverse osmosis was adopted in an iron and steel enterprise to treat the reverse osmosis brine produced in reclaimed water reuse engineering for supplementary water of circulating water system in coking plant. The actual operation results show that the brine treatment system operates well and the treatment process is reasonable, the water production rate of the project reach 78.8% and the direct operating cost is 4.62 yuan/m3. The reclaimed water quality meets criteria for process and product water quality in The Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses(GB/T 19923-2005) and the final ultra-concentrated water quality meet the specific water pollutant discharge limits in Discharge Standard of Water Pollutants for Iron and Steel Industry (GB 13456-2012). The final ultra-concentrated water is used for scouring slag or mixing into sintering ingredients to achieve the goal of brine zero discharge.
